RoboProp

Populated RoboProp

RoboProp is an advanced robot controller board with an integrated L298 full H-Bridge for driving two DC motors.

RoboProp Features:

  • 4.000″x3.050″ standard form factor with standard mounting hole pattern
  • Designed to fit onto BOE-BOT as an upgrade
  • Designed to fit Dagu “Mr. Basic” and “Arduino Motor” robot platforms
  • Parallax Propeller processor with eight 32 bit cores running at 100Mhz
  • 64KB EEPROM
  • uSD for data logging and program storage
  • L298 full H-bridge driver with up to 2.5A drive with large heat sink per motor (3A peak)
  • optional current sense resistors
  • 8 channel / 12 bit ADC for 3-pin 5V sensors (MCP3208)
  • up to 24 channels for servos or digital inputs
  • Mikronauts I2C connector for upcoming Mikronauts I2C modules
  • HCOMM connector for programming via Propeller Plug, or Mikronauts SerPlug
  • EXP connectors for breadboards and Mikronauts modules
  • can use FlexMem for SRAM/FLASH/FRAM/MRAM memory expansion (uses 6-8 I/O pins)
  • can add upcoming MCP3208 module for an additional 8 analog input channels (uses 4 I/O pins)
  • can stack on other Mikronauts CPU boards and breadboards with stacking headers for EXP1/EXP2
  • two small high-density prototype areas
  • screw terminals for Vin/GND, MotorA, MotorB
  • on-board 5V and 3.3V regulation
  • RoboPropDiag diagnostic software for testing and exercising ADC/SERVO/L298 features included
  • uses OBEX objects for pwm, servos and ADC
  • fsrw26 modified for RoboProp’s uSD settings included
  • extra mounting holes for sensors and other platforms

Notes:

  • four servo / IO channels are shared with the L298 motor driver
  • four servo / IO channels are shared with the uSD socket

“Pollo”

Pollo is my nickname for my youngest nephew (Mateo), and also the name of one of my RoboProp based robots.  Pollo started out as a standard BOE-BOT, but he’s grown up a lot…
BOE-BOT Upgraded with RoboProp

“Marco”

Marco is Pollo’s older brother (for some reason my sister did not take my suggestion for Mateo’s name). Marco is based on the two wheel drive / two encoder Dagu Rover 5 platform, controlled by RoboProp, with a lot of extra goodies.
Marco: RoboProp used to control a DAGU Rover 5 platform
